ENVELOP.

Specification of Letters Patent.

' Patented June 8, 1915.

Application filed December 8, 1910. Serial No. 596,258.

To all whom it may concern: Be it known that I, JAMES LOGAN, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Envelops, of which the following is a specification.

My invention relates to improvements 1n the class of envelops having separate div sions or pockets in the same envelop, and 1t has for its objects to provide an envelop of this class which may be constructed with a smaller amount of paper for each envelop than is commonly required; to provlde a manner of guinming which shall be more secure for the use of the envelop in churches and Sunday schools as a collection envelop for receiving offerings; and to make a double pocket envelop which shall more nearly correspond in details of construction to the ordinary envelop of similar construct1on,thereby reducing the expense and difi'iculty of manufacture of this class of envelops. I attain these objects by the construction of an envelop as illustrated in the accompanying drawing, in which- Figure 1 is the blank from which my 1m- .proved envelop is made, showing the inner side of the blank. Fig. 2 is the blank with the two end flaps folded into position. Fig. 3 is the completed envelop. Fig. 4 is a longitudinal sectional view on the line 44, Fig. 3.

Similar reference characters refer to similar parts in the different figures.

The envelop blank shown extended in Fig. 1 comprises end flaps 1 and 2 and a back flap 3, arranged to be folded on the broken lines a, b 0 against the body portion, the folding taking place in that order. During the operation of folding, the seal flap 5 is creased and folded on the broken line in the usual manner. The end flaps 1 and 2 are of somewhat greater length than one half of the body portion 4 so that end flap 1 when folded will extend beyond the center of the body of the envelop, and the end flap 2 when folded will extend over the end flap 1 and beyond its gummed portion. Prior to folding, gum is applied at 8 and 9 to the outer ends of each end flap, and when folded the gummed portion 8 is brought into contact with the body portion 4 at '10, Fig. 4, just beyond the center of the body portion of the envelop. When the end flap 2 is fold- When the end flaps l and 2 have been folded and attached as above described, the back flap 3 which is provided with a gummed edge 12 is folded over the lower edges of the end flaps 1 and 2 and securely attached thereto, as shown in Fig. 3. The folding of the back flap 3 forms the bottom of both pockets A and B, and it also reinforces the gummed joint between the two end flaps, serving as a longitudinal strip adapted to resist any strains exerted upon the end flaps. The seal flap 5 which is also gummed at its edge 13 is folded over the end flaps and attached thereto inclosing the pockets of the envelop, serving likewise to reinforce the end flaps and resist any longitudinal strain applied thereto.

I am well aware that it is not new to fold w an envelop blank to form two or more pockets in the envelop, and I do not claim such broadly.

A distinguishing feature of applicants envelop consists in the employment of the end flaps substantially the same as used in the ordinary commercial envelop. These end flaps are folded in succession upon the rectangular body portion of the envelop and attached at their ends, one end flap to the body of the envelop at one side of its center,

in the folding mechanism of the machine,

and this is accomplished without requiring the application of adhesive material to the body portion of the envelop, or its application to more than one side of the blank. As will be readily apparent, this change is made simply by omitting the application of gum to the edge 8 of the end flap 1, whereby when the blank is folded, in precisely the same manner as heretofore described, and the gummed portions are attached, there is produced an envelop providing but a single receptacle or pocket. The appearance of the envelop when completed does not depart from that of the ordinary commercial envelop.

I claim, 7 1. A single envelop provided with two separate pockets, said envelop being formed from a blank having a rectangular body portion, two end flaps of substantially the same width as said body portion, and of a length to extend beyond the center of said body portion and to overlap each other when fold ed in succession upon said body portion, with the free end of one of said end flaps attached to the body portion and with the free end of the other end flap attached to the first folded end flap, a back flap extending the entire length of the envelop and folded upon and attached to said end flaps, and a gummed seal flap extending the entire length of the envelop. r

2. A two pocket envelop, formed from a blank having a rectangular body portion, two end flaps of substantially the same width as the body portion and folded thereon in succession, with the free end of the first folded end flap attached to the body portion beyond the center line thereof, and with the free end of the other end flap attached to the outer side of the first folded end flap, on the other side of the center of the body portion, a back flap extending the entire length of the body portion and folded over and at tached to the outer sideof both of said end flaps, and a gummed seal flap extending the entire length of said body portion and common to the two pockets formed by the two end flaps and the back flap.
